Note: Other models of MAX series share the same label design with MAX50KTL3 LV,
only with different model name and parameters, detail parameter please refer to
specification in Chapter 10.
The MAX series inverter works as follows:
1>The PV panels gather solar to generate DC power to inverter.
2>With input current detection circuit, it can monitor all the PV panels' working status
and use MPPT to track the maximum power point.
3>With inverter circuit change DC power to AC power, and feed power back to grid per
grid reuqirement.
4>With output isolation relay can isolate AC output and grid, if anything goes wrong on
either inverter side or grid side, isolation relay can disconnect inverter immediately.

Description
1>Do not unpack the inverter and store it in a ventilation dry place .
2>Keep the storage temperature at -25℃ - +60℃ and humidity at 0-95%.
3>A maximum of four inverters with package can be stacked.
4>If the inverter has been long-term stored, inspections and tests should be conducted
by qualified personnel before it is put into use.
After being stored for a month or longer, the inverter's time and date
could be wrong, you need set the time and date before using, for
more details please refer to Chapter 7.1 inverter commissioning.
